Perfect for slightly narrowed 9 inch

Perfect match (once cut down) to my Speedway motors fabricated 56" ford 9 inch. 31 spline with pre-installed bearings not only saved me time, but the price is hard to beat ! Cut down nicely with chop saw and beveled the splines a touch to help engage nicely into the 3rd member.
